URl redirection issue in Django 2 - django

Question

I'm new to Django and trying to build a web app with the following structure. I need your help to understand what Im doing wrong.
The flow of the application is shadesProductUploader.urls will forward '' to authSection for login and after a successful login user should be redirected to mainSection 'home/'.
Urls.py files are
shadesProductUploader.urls
from django.contrib import admin
from django.urls import path,include
urlpatterns = [
path('admin/', admin.site.urls),
path('',include('authSection.urls')),
]
authSection.urls
from django.contrib import admin
from django.urls import path, include
from . import views
app_name = 'authSection'
urlpatterns = [
path('', views.login_view, name='login'),
]
mainSection.urls
from django.contrib import admin
from django.urls import path,include
from . import views
app_name = 'mainSection'
urlpatterns = [
path('home/', views.home),
]
and the view.py in authSection
def login_view(request):
next = request.GET.get('next')
form = userLoginForm(request.POST or None)
if form.is_valid():
username = form.cleaned_data.get('username')
password = form.cleaned_data.get('password')
user = authenticate(username=username,password=password)
login(request,user)
if next:
return redirect(next)
context={'user':user}
return redirect('home/')
return render(request, 'login.html', {'form': form})
after a successful login I get this error.
What Am I missing? Not sure why I see a Url of home/ home/

Answer 1

Update shadesProductUploader's main section url like this:
urlpatterns = [
path('',include('mainSection.urls')),
... # other urls
]
And change in mainSection urls like this:
urlpatterns = [
path('home/', views.home, name="home"), # <-- added name here
]
And in view, use it like this:
if next:
return redirect(next)
context={'user':user}
return redirect(reverse('home'))
Here, we have named our url as home. And we got the url using reverse.
